Description
・ 膨張性黒鉛が、流動床において或いは既に最終成形型内で、適切な熱の供給のもとで不完全膨張され、続いて、成形型内において、高温にされて膨張が終わらされる。
・ 適切な熱の供給のもとで不完全に膨張された膨張性黒鉛が、成形型内で半製品の形に圧縮され、続いて、成形型内において、高温にされて膨張が終わらされる。
・ 成形形内における膨張性黒鉛の湿り処理が、熱の供給下において黒鉛を膨張させる。
2枚の織物ベルト間で粉末状黒鉛膨張体を連続して圧縮することで、厚さ25mmのシート板を製造した。この板から、長さ30cm、幅30cmのサンプルを切り出し、その密度を測定した。その結果、0.027g/cm3の値を得た。更に、x、yおよびz方向における比熱伝導率と比電気抵抗を測定した。その結果を、次の表1にまとめて示す。
30×70cmの面積を持つ層複合建材部品を製造した。それを図2に示す。この複合体は、厚さ18mmの硬質繊維板4と、圧縮された黒鉛膨張体から成る厚さ9mmの熱伝導板1と、厚さ1mmの孔開き鋼板5とから成る。熱伝導板の背面の硬質繊維板4は断熱のため、正面の孔開き鋼板5は見栄えの改善のために用いる。硬質繊維板と熱伝導板は互いに貼着してある。孔開き鋼板は、層複合体をその長手側面で取り囲み、硬質繊維板4に存在する長手溝6、6′に固定保持されている。この層複合体は、例えば空調天井を構成するのに適する。熱伝導板1の硬質繊維板4と反対側の表面に、アルキメデス状スパイラル7の形に巻回した直径6mmのプラスチック管(以下で加熱スパイラルと呼ぶ)を、これが板表面と面一になるように埋設した。スパイラルの最外側ターンの直径は21cmとした。スパイラル7を板1のほぼ中央に配置した。即ち、スパイラル7の最外側ターンと板右側縁との距離を、板左側縁との距離とほぼ同じにし、最外側ターンと板上縁との距離を、板下縁との距離とほぼ同じにした。
Claims (5)
- 圧縮された膨張黒鉛を、壁暖房、天井暖房、床暖房又は空調器における熱伝達のために使用する使用方法であって、
前記圧縮された膨張黒鉛が結合剤を含まず、かつ、
前記圧縮された膨張黒鉛がシート板であり、かつ、
当該シート板は、全部が膨張黒鉛からなり、その厚さが8mm〜50mmであり、かつ、
前記圧縮された膨張黒鉛の密度が0.01g/cm 3 〜0.5g/cm3である、
方法。 - 請求項1に記載の方法であって、
前記シート板の表面に対し平行な熱伝導率が、前記シート板の表面に対し垂直な熱伝導率に比べて少なくとも50%高い、
方法。 - 請求項2に記載の方法であって、
前記板表面に対し平行な熱伝導率が、少なくとも5.5W/m・Kである、
方法。 - 請求項1から3までのいずれか1項に記載の方法であって、
前記シート板の厚さが15mm〜40mmである、
方法。 - 請求項1から4までのいずれか1項に記載の方法であって、
前記シート板の密度が0.05g/cm 3 〜0.25g/cm3である、
方法。
